What are the causes of car steering deviation?

How are car classes determined?

Automobile classes are generally divided into six levels: A00, A0, A, B, C, and D. They can also be classified by engine displacement: micro cars (displacement below 1L), compact cars (displacement 1.0~1.6L), midsize cars (displacement 1.6~2.5L), executive cars (displacement 2.5~4.0L), and luxury cars (displacement above 4L). Below is a detailed classification: 1. A00 class: A00 passenger cars have a wheelbase between 2 to 2.3 meters and engine displacement below 1 liter, such as the Alto and Smart. 2. A0 class: A0 passenger cars have a wheelbase of 2.3 to 2.5 meters and displacement of 1 to 1.5 liters, typical examples being the Sail, Fit, Polo, Verna, and Fiesta. 3. A class: A-class cars have a wheelbase ranging from 2.5 to 2.7 meters and displacement around 1.5 to 2.0 liters, such as the Focus, Sagitar, Corolla, and Audi A3. A-class cars are the most commonly used family cars in China. 4. B class: B-class midsize passenger cars have a wheelbase of about 2.7 to 2.9 meters and displacement from 1.8 to 2.5 liters. The B-class market has gradually become the main battleground for domestic automakers, with models like the Mazda6, Accord, Mondeo, Sonata, Audi A4, Passat, and Toyota Camry belonging to this category. 5. C class: C-class executive cars have a wheelbase of about 2.8 to 3.0 meters and engine displacement from 2.3 to 3.0 liters. The most renowned C-class cars in China are the Audi A6, BMW 5 Series, and Mercedes-Benz E-Class. 6. D class: D-class luxury passenger cars are mostly grand in appearance, with extremely spacious interiors and powerful engines. Their wheelbase is generally over 2.8 meters, and displacement is mostly above 3.0 liters. Common D-class cars include the Mercedes-Benz S-Class, BMW 7 Series, Audi A8, and models from Rolls-Royce and Bentley.

Where to Refill Windshield Washer Fluid in a Mercedes-Benz?

Mercedes-Benz windshield washer fluid is refilled at the rear side of the engine hood pressure strut, with the filler cap marked by a washer symbol. Windshield washer fluid is a consumable item with no fixed replacement interval, depending on the frequency of use by the driver. Method for refilling windshield washer fluid: Turn on the wiper switch to spray out the old fluid first; when the wiper nozzles stop spraying, add a small amount of new fluid into the filler port. Then, turn on the wiper knob to clean out the remaining old fluid solution. When the nozzles stop spraying for the second time, add approximately 4L of windshield washer fluid, completing the refilling process. Functions of windshield washer fluid: Cleaning performance: Windshield cleaner is formulated with various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing functions, thereby achieving cleaning and stain removal; Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze effects and quickly dissolving frost; Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring clear and transparent windshields with unobstructed visibility; Anti-static performance: After cleaning with windshield cleaner, substances adsorbed on the glass surface eliminate static charges on the glass; Lubrication performance: The ethylene glycol in the windshield cleaner has high viscosity, providing lubrication to reduce friction between the wipers and the glass, preventing scratches; Anti-corrosion performance: Windshield cleaner contains various corrosion inhibitors, posing no corrosive effects on any metals, and is absolutely safe for automotive paint and rubber.

Should I engage the handbrake or shift to neutral first when parking?

Generally, the normal parking procedure is to engage the handbrake first and then shift to neutral. Below are some related driving techniques: 1. When starting the vehicle: Let the engine idle for about half a minute, then depress the clutch, shift to first gear, simultaneously press the foot brake with your right foot, release the handbrake with your right hand, and slowly release the clutch. 2. While driving: When the speed reaches 15-20 km/h, shift to second gear; when reaching 25-30 km/h, shift to third gear. 3. Decelerating to stop: Once the brake reduces the vehicle speed to a safe level, you can depress the clutch, engage the handbrake, and shift to neutral.

What is the difference between water beads and no water beads on car paint?

The difference between having water beads and no water beads on car paint includes the following points: 1. Waterproof performance: Water beads on the car body indicate that the clear coat layer on the surface is intact, providing strong waterproofing. This causes rainwater to instantly contract into beads and slide off, effectively preventing the formation of water stains. The clear coat layer is a solvent-based system, including medium and high solid acrylic resin/melamine resin curing systems. 2. High-temperature resistance: Cars driven or stored outdoors for long periods are prone to paint aging and fading due to sunlight. A paint surface with water beads can reflect some of the light, effectively preventing paint aging.

Where is the car's spark plug located?

The spark plug in a car is generally located inside the engine cylinder. It can be clearly seen after removing the high-voltage ignition coil. Spark plug replacement procedure: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check for external debris such as leaves or dust and ensure thorough cleaning. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires according to the firing order, then secure the cover. Spark plug replacement interval: Under normal maintenance conditions, replacement is recommended every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the owner's manual. Platinum spark plugs should be replaced at 40,000 km, standard nickel alloy spark plugs at 20,000 km, and iridium spark plugs between 60,000-80,000 km.
